To aZZ whom it may concern:

Be it known that we, JOHN cuorr and MAUnrrz G. INDAHL, citizens of theUnited States, residing at Philadelphia, in thecounty of Philadelphiaand State of Pennsylvania, have invented certain new and usefulImprovements in Record-Strip This invention relates to improvements in;t io ra )lllC com osin machines wherein .ll 2: l

such as a finger key, and it has for-its'pr'in- I cipal object toprovide means whereby the v mechanism responding to a selective or des-'ignating member when once set n motion 1S continued in action and'causedto automatically repeat its functions until arrested.

a repeat action. of

'ures ind cate the same-parts.

A machine embodying this kind is illustrated in Patent No. 938,298,dated Oct. 26, 1909, wherein a special or 're- -peat key is coupled withthe starting mech- I anism of the punch and -feed motor in a manner tocause the starting mechanism to be automatically actuated by and duringthe return stroke of said motor, therebyconverting the otherwisesingle-acting motor into one capable of continuous operation so long asthe conditions produced by the depression of the repeat key aremaintained.

The present invention is primarily de-, signed to provide a repeatmechanism which may be employed in connection with the standardequipment or in connection. with the mechanism of Patent No. 944,405,dated December :28. 1909, without extensive change or alteration andwhich will be effective for giving repeatdesignations of any characteror characters on the key board by the simple,manipulation of thefkeyindicating the desired character or characters in connection with arepeat-key which throws the repeat mechanism into action.

Referring. to the accompanying drawings,+-Figure l is a sectionalelevation'of a port1on of arecord' strip composing machine, many of thewell knownparts being ignating mechanism,.especially designed for use 1ncombination therewith, and hence it is omittechlbut which will bereadily understoodfrom the parts indicated -'in the drawings ,inconnection with the mechanism shown in PatentNo.'-94t,el05,beforereferred to.

Like reference numbers in the several figconnections between the keybars and the valve controlling-bars; the valve controlling bars providedwith projections 17 6 with which the bails 175 on the rocker framescooperate; and the key bars which cooperatewith the upper barsof saidbails having the usual downwardly extending pro1ections thereon. Thearrangement of projections on the bars corresponds to the well knownarrangement for effecting the selective operation of the valvescontrolling the punches. The valve stems are indicated at 170. and itwill be understood that when said valvestems are moved longitudinallybythe' longitudinal movement of the valve operating bars 173, pressurewill be admitted to the corresponding cylinders of the pneumatic. motormechanism for advancing the punches and making the proper selectivedesigna- The paper feeding mechanism corresponds Icontroller bars. Fig-5is aperspective view to that of the before-mentioned patent and at 146there is indicated the valve for controlling the admissionof pressurebeneath one or the other of'pi'stons 137 and 138, which pistons areconnected with a rockin frame 139. y

The foregoing reference numbers all correspond to reference numbers oncorre sponding parts of the mechanism in said- .patent, from which thedetail construction and operation will be readily understood,

In the operation of such mechanism when a proper valve. operating bar ismoved longitudinally to operate its valvev stem, the corresponding punchwill be advanced, whereupon the valve 1&6 will be moved to admitpressure beneath thevpist'on 138 to retract the parts preparatory for anewfeed fiend-rewind the motor spring of the paper v take-up portion ofthe paperfecding mech anisirnand upon the retraction of the punch ,thevalve 146 will be moved back to itsnormal 'positionand admit airunderneath piston157 so as to'advance the paper onerstep and; thissequence of operation is repeated every time a key in the key board isdev 3 pressed and again released; v

-' Themechanism for carrying into effect the repeat action of thepresent invention makes provision whereby when a selective designatingkey or device such as one or the other of the keys 180 is operated incon unction-with a repeat key or device, the key 15,

for example, and the keys held depressed, the valve stem and valvenormally operated by the selective designating key will be operated aplurality of times, thus effecting the repeated operation of thedesignated punch or punches. Tocarry this into effect in a simplemanner, the valve operating bars are preferably made in two sections 173and 1 sion of the spring 10, the sections of the bar are held in theirproper relati e position with sufiicient rigidity to actuate the valve,and their relative position is determined by the engagement of lugs 13and 14 projecting: downwardly from the sections and offset to intersectas shown in Fig. 4. With this arrangement, even though the design. tingkey be held depressed, the valve stem engaglng section of the bar may bemoved reverselv *against the tension of the spring 10, and a motormechanism is provided for so moving the section periodically 1n timewlth the paper feed movements, and under the control' of a repeat keyindicated in Fig.1 at 15. This repeat key 15 may correspond. inconstruction to the designatingkey 180 of the key board, and is adaptedto coiiperate with and advance 'a repeat key bar 16 correspondmg in formand arrangement to the designating key bars but having no downwardlyextending projections for cooperation with the bails of the rockerframes.

At its inner end the repeat key bar is adapted to poiiperate with andactuate a repeat key lever 17 journaled in bearings at its lower edge,as shown in Fig. 2, and having an arm 17 resting behind a projection 18on a bar 18 mounted to slide in the key board frame in manner similar tothe valve operating bars before referred to; The end of the bar 18 isadaptedto coiiperate with mechanism for controlling the repeat motor,that is to say, when advanced by the operamotor and the latterimmediately begins to operate in such wiseas'to effect an intermittentoperation of the valves which have beendesi'gnated by the selectingdevices of valve actuating bars.

The repeat motor and parts immediately associated therewith are allpreferably secured to the valve casing and can be removed with it; thus,the key board as a whole is formed in units, as it were, which may beseparately adjusted and then assembled togetherin the casing to form acomplete machine. The motor mechanism referred to embodies a pair ofoppositely disposed cylinders 19 provided with pistons 20.

' tion of the repeat key it releases the repeat As will be presentlydescribed, pressureis supplied to the cylinders 19 alternately in timewith the pressure supplied to operate the pistons 137 and 138' and thepistons 20 will when permitted to operate be reciprocated in time withthe punches and paper feed. Between the proximate faces of the pistonsthere is mounted the end of an arm 21 projecting from a rocking frame'22 journaled in bearings supported from the valve casing and having atransverse member or bar 23 normally occupying a position in front ofthe downward extensions 173 of the "alvepperating bars 173. The normalposition of the rocking frame and transver e bar 23 is such that themovement of the valve operating bars is not interfered with and when norepeat action is desired the said bars operate in all respects as in thecommercial machine and patent hereinbefore referred to, but when therepeat action is desired the repeat motor is set into operation in timewith the paper feed and the rocking frame is thereby oscillated, wherebythe transverse bar 23 periodically pushes the yielding forward sectionsof the valve opera-ting bars reverselv or against the tension of thesprings 10, the number of such movements depending upon the time thekeys are held depressed and the repeat motor is allowed to continue inaction.

For normally restraining the operation of the repeat motor'and holdingthe parts in a definite position when brought to rest, a lock or catchis provided which is adapted to be released by the repeat bar 18 whenadvanced by the operation of the repeat key.

The simple and preferred arrangement adopted embodies an angle lever24'journaled at an intermediate point on the repeat motor frame andhaving one arm extending at 25 into position immediately in front of theend of the repeat bar" 18 while the other arm is provided with ashoulder 26 to cooperate with an adjustablestop formedby a setscrew 27mounted in an arm 28 on .shoulder26 is in engagement with the stop 1 r27 the oscillatory frame 22 will be held in the position shown in Fig.1, that is to say,

the oscillatory frame 22. The relation of the parts. is such that whenthe catch or in its inoperative position and with the piston 20of thelower cylinder 19 retracted.

, The latch formed by the angle lever 24 is held in the position lastreferred to by a spring 29 and is released from its engagement with theoscillatory frame to permit the repeat motor to operate, by the movementof the repeat bar 19 when advanced b the repeat key 15.- r v Thearrangement described normally holds the oscillatory frame in a definiteposition at all times when the repeat key is not depressed, thusinsuring accurate count ing of the registering mechanismof thekeypreferably of cylindrical formation, open at the inner ends toreceive projections 35 on screw plugs 36 forming the rear cylinderheads. Said projections do not fit the chambers in the pistons tightly,but they form stops for limiting the rearward movement of the pistonsand are susceptible of adjust ment with the plugs 36 and may be fastenedin adjusted position by lock nuts 37 on the plugs.

The proper timing of the movements of the repeat motor may be bestsecured by a control of the air pressure through the operation of thepunches. In the commercial machine as well as in the machine of patent,a valve 146 of the D-type is operated by a 2 rock shaft having a bailoverlying shoulders on the punch bars, to admit pressure alternately tothe cylinders 137 and 138 and this valve may be utilized to similarlycontrol the admission of pressure to the cylinders of the repeat motor.An arrangement of this kind isshown in Fig. 1, where ducts or pipes 52lead from the valve to the cylinders of the repeat motor. A convenientarrangement is to extend the ducts 52 from the bottoms of the cylinders"137 and 138, although-it is obvious that they may be branchedat anydesired point from the ducts leadin from the valve. Y

It is not important that the same valve be employed for admittingpressure to both the repeat motor and cylinders-137 and 138,

and in Fig. 5 an arrangement is shown in which an independent valve isemployed.

In the arrangement last referred to the usual rock shaft and bail areshown at 40 and on the opposite side of the punch bars 41 there is asecond rock shaft 42 having a bail 43 in position for cotiperation withthe shoulders on the punch bars which engage the bail 40. The bail 43islifted by the punch bars and returned by elastic piessure preferablysupplied by constant air pressurein a cylinder 44 in which works apiston connected by rod 45 with a rearwardly extending arm 46 on therock shaft.

The rock shaft carries an arm 47 having a cam slot 48 therein for thereception of a stud on one arm 49 of an-angle lever pivoted on theframe. The other arm 50 of the angle lever engages and operates-2i valve51 for controlling the admission of pressure through the ducts 52 to thecylinders of the repeat motor. the valve 146 before referred to but isoperated by the'rock shaft and bail 42 and 43 while the valve 146 isoperated by the rock shaft and bail 40. \Vith this arrangement theoperation of the repeat motor may be timed in any preferred relation tothe punch movements to secure the most desirable or highly efficientaction.

In operation the designating key and re-v peat key are both depressed oroperated and the normal action of the designating key on its selectormotor is repeated by the action of the 'repeat motor.

From the foregoing description it will be seen that the valve operatingbars form in effect a plurality of key controlled selecting devices, andthe repeat motor while de The valve 51 is similar to scribed as 'one'dependent for its operation the desired punches will be advanced pri--marily through the operation of their nor mal designating keys and therepeating opby Letters Patent of the'United States, is:-:'-
